Traditionally, this method considers a rigid configuration, where the position and orientation of the light emitter with respect to the camera are known and calibrated beforehand. In this paper we propose a new omnidirectional structured light system in flexible configuration, which overcomes the rigidness of the traditional structured light systems. We propose the use of an omnidirectional camera combined with a conic pattern light emitter. Since the light emitter is visible in the omnidirectional image, the computation of its location is possible. With this information and the projected conic in the omnidirectional image, we are able to compute the conic reconstruction, i.e., the 3D information of the conic in the space. This reconstruction considers the recovery of the depth and orientation of the scene surface where the conic pattern is projected. One application of our proposed structured light system in flexible configuration consists of a wearable omnicamera with a low-cost laser in hand for visual impaired personal assistance. 000058511 536__ $$9info:eu-repo/grantAgreement/ES/MINECO/DPI2012-31781 000058511 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000058511 590__ $$a2.048$$b2013 000058511 591__ $$aINSTRUMENTS & INSTRUMENTATION$$b10 / 57 = 0.175$$c2013$$dQ1$$eT1 000058511 591__ $$aCHEMISTRY, ANALYTICAL$$b36 / 75 = 0.48$$c2013$$dQ2$$eT2 000058511 591__ $$aELECTROCHEMISTRY$$b15 / 27 = 0.556$$c2013$$dQ3$$eT2 000058511 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000058511 700__ $$aPuig , L. 000058511 700__ $$0(orcid)0000-0001-5209-2267$$aGuerrero, J.J.$$uUniversidad de Zaragoza 000058511 7102_ $$15007$$2520$$aUniversidad de Zaragoza$$bDepartamento de Informática e Ingeniería de Sistemas$$cIngeniería de Sistemas y Automática 000058511 773__ $$g13, 10 (2013), 13903-13916$$pSensors$$tSENSORS$$x1424-8220 000058511 8564_ $$s599897$$uhttps://zaguan.unizar.es/record/58511/files/texto_completo.pdf$$yVersión publicada 000058511 8564_ $$s80228$$uhttps://zaguan.unizar.es/record/58511/files/texto_completo.jpg?subformat=icon$$xicon$$yVersión publicada 000058511 909CO $$ooai:zaguan.unizar.es:58511$$particulos$$pdriver 000058511 951__ $$a2017-05-04-09:14:47 000058511 980__ $$aARTICLE
